A big thank you to anyone who helped me with the question on using urea
crystals and 1% toluidine blue for demonstrating basal cell carcinoma
tumors.  I have been using it for about 1 to 2 weeks and I see a marked
improvement in the intensity and contrast in the staining-mostly the
contrast between the pink/purple stained mucinous substance around the dark
blue basal cell nodules of cancer.  Doctor hasn't said anything yet but I
have no complaints.  Thanks again.
